Climbing rose plant named &#39;poulcy015&#39;

ABSTRACT

A new garden rose plant of the climbing class which has abundant, red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL DESIGNATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulcy015’

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, an unnamed seedling.

The two parents were crossed during the summer of 1998 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulcy015’, originated as a single seedling from the stated cross.

The new variety may be distinguished from its female seed parent by flower size. The female seed parent has large very double flowers while the new variety has smaller flowers with 20 petals.

The new variety may be distinguished from its male pollen parent by growth habit. The male parent plant is compact and bushy, while the new variety has an arching habit.

The objective of the hybridization of this rose variety was to create a new and distinct variety for container and garden use with unique qualities, such as:

1. Uniform and abundant red flowers;

2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;

3. Exceptional disease resistance.

4. Reduced apical dominance in flowering habit. The new variety consistently produces flowers evenly from the lower branches to the top of the plant.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulcy015’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1998 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulcy015’ was selected in the spring of 1999 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulcy015’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 1999. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulcy015’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulcy015’, as observed in its growth in a field nursery in Benton County Oreg. Observed plants are 3 years of age, grown on rosa multiflora understock. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poulnorm’, U.S. Plant Pat. No. 12,522 are compared to ‘Poulcy015’ in Chart 1.
